FIREARM.

Specification of Letters Patent.

Patented Nov. 2, 1915.

Application filed March 28, 1913. Serial No. 757,327.

To all whom it may concern:

Be it known that I, Ann-run P. CUnTrs, a citizen'of the United States, and a resident of Fulton, in the county of Oswego and State of New York, have invented a new and useful Firearm, of which the following is a specification.

This invention relates to firearms and has for its object the production of a part1cularly simple and efficient construction of firing pin and means for retaining the fir ng pin from displacement; and the inventlon consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure l is a side elevation, partly broken away and partly in section, of one form of my firing pin and contiguous parts. Fig. 2 is a section on line A-A--, Fig. 1, the firing pin being shown in elevation. Fig. 3 is an elevation of the removable side or look plate.

I have here illustrated my invention as embodied in a break-down shot gun and in the drawing, 1 designates the frame and 2 the barrel which is hinged to the frame in the usual manner, the frame including the usual block 3 located at the rear of the barrel and formed with a lengthwise passage 1 which opens through its front and rear faces.

5 is the firing pin slidable in the passage 4.

6 is the removable side or look plate held in position b suitable fastening means as screws, this ring pin being arranged and shaped to be held in position by the side plate.

The side or lock plate 6 is arranged wlth its outer face flush with the outer face of the frame, Fig. 2, in the usual manner, and as here shown the side plate is formed with an edge portion which extends across the rear end of the passage 4% and partly closes the same, as seen in Fig. 2, and which coacts with the body of the firing pin to prevent the same from displacement.

As here illustrated the side plate 6 is formed with an upwardly extending portion 7 closing the space of the frame in the rear of the block 3, this portion having a forwardly facing edge 8 which extends across and partly closes the rear end of the passage 4.

Preferably the passage 4: includes a cylindrical portion and a reduced tapered front portion, and the firing pin 5 includes a cylindrical body slidable in the cylindrical portlon of the passage 4., and a tapered front portion or point 9, movable through the tapered front-portion of the passage l, and the edge 8 of the side plate 6 engages the rear face of the cylindrical body portion of the firing pin 5. The firing pin is also provided with a, rearwardly extending reduced portion 10 arranged to receive the blow of the hammer 11, said portion 10 lying at the inner sideof the side plate and projecting to the rear of the edge 8 of the side plate. The passage 4 is shown as inclined upwardly toward its front end out of a horizontal line.

In guns of different sizes that is guns having barrels of larger bore the passage a will be less inclined or horizontal.

The constructions and arrangements herein described are particularly simple and durable and provide for the ready removal of the firing pin upon the removal of the side plate.

WVhat I claim is:

1. In a firearm, a frame formed with a passage extending forwardly and rearwardly and open at its opposite ends, a firing pin movable in the passage, and a removable side plate, the firing pin being arranged to be held from displacement out of the passage by the side plate, substantially as and for the purpose described.

2. In a firearm, a frame formed with a lengthwise passage open at its opposite ends, a firing pin movable in the passage and formed with a rearwardly facing shoulder, and a side plate having a portion projecting in the path of the shoulder for normally preventing displacement of the firing pin, piulstantially as and for the purpose speci- 3. In a firearm, a frame formed with a lengthwise passage open at its opposite ends, a firing pin slidable in the passage, and a removable side plate, the passage being arranged so that an edge portion of the side plate extends across and partly closes the rear end thereof, and thereby retains the firing pin in the passage, substantially as and for the purpose set forth.

4. In a firearm, a frame formed with a lengthwise passage open at its opposite ends, a firing pin movable in the passage, and a side plate having a forwardly facing edge, the passage being arranged so that its rear end is partly closed by said ed ge of thesi'de plate and the firing pin retained in the passage by the side plate, substantially as and for the purpose described.

5. In a firearm, a frame comprising a blocli having 'a lengthwise passage opening throu h its front and rear faces firin tpin slidable in the passage, and a side plate having an upwardly extending portion Tarranged the rear of the bloekythe passage beinglocated so that its: rear end ispartly closed by the front edgeof the upwardly Wis passage opening through front and-rear facesthereon-the;passagehavinga rear cyli'ndrical' portien atapfllfid front por- .tion,ia firing pin having aicylindricalbody slidable' in' the cylindrical iportionlofthe passage, and a tapered. portion movable in the tapered p rti n of the; passage the firing Pin. also includ ng a a wardlyextending redu ed p r i n at i s rear. end fOIiIGC l-ViIIg theblow ogfgthe hammer, and za'sideplate havingan edge portion thereof arranged to extend across and partly close the rear end of 'saidpas'sage and coa'ctwith the-rear face of the body -ofthefifihg pin, to prevent displacement of the firing pin, the reduced rear end of the firing pin extending in the rear of said edge portion, substantially as and for the purpose specified.
